Hi team,
We have an issue with our MTR's where the GC8's screen that is connected via USB with our NUC will go black and regardless of what we do not come back online unless switched out with another GC8.
We have deleted the drivers and removed from Windows all together but unless we hot swap the screen will not come back on.
Is there any way to update these systems or are they standard out of the box?

Hello @UCEnginfear ,
Welcome to the Poly Community.
It's always useful to provide as much information in a 1st post as possible. Therefore what is the software version of the MTR?
Is this a new working installation or is this an existing "old" Installation? Have you tried factory resetting the GC8 (Power off, push small pin into restore hole on GC8 and power back on?)
The GC8 is not super informative in what it is doing and can take up to 40-45 minutes during an update with no UI at all.
The next step would be Poly support with Lenovo.
